Battersea’s final build-out highlights the financing value of flexible phasing

A significant final chapter

Construction Enquirer reports that plans have been submitted for the final 3.2m sq ft build-out at Battersea Power Station. Studio Egret West has overhauled Rafael Viñoly’s 15-year-old masterplan for the undeveloped portion of the 42-acre riverside site, with the proposals expected to nearly double the development completed so far.

The scale is notable, but the restructuring of the masterplan is more instructive for developers and funders. Future phases are now arranged as clusters of smaller buildings, connected by streets, lanes, courtyards and passages, rather than larger development blocks. The proposed mix includes housing, offices, shops, leisure and cultural space.

Smaller plots can support more responsive delivery

Breaking a large masterplan into smaller components can create greater flexibility around sequencing. Individual buildings or clusters may be progressed according to planning status, occupier demand, construction capacity and available capital, rather than requiring the entire remaining site to move forward as a single proposition.

From a financing perspective, this can make it easier to define discrete phases, budgets and repayment strategies. It may also widen the range of potential funding structures by separating residential, commercial and community-led elements. However, smaller plots do not automatically mean simpler delivery. Shared infrastructure, public realm, access routes and dependencies between phases still need to be allocated clearly within cost plans and facility documentation.

Mixed use requires differentiated underwriting

The refreshed plan responds to changing relationships between work, living and leisure, according to Battersea Power Station Development Company chief executive James Saunders, as quoted by Construction Enquirer. For finance providers, that diversity can broaden the scheme’s sources of demand, but it also introduces distinct underwriting considerations.

Housing, offices, retail, leisure and cultural uses have different delivery periods, income profiles and routes to exit. A credible financing strategy therefore needs to consider how each component contributes to the wider business plan, rather than relying solely on the headline scale of the masterplan. Lenders and investors are likely to focus on the timing of expenditure, the treatment of shared costs and the extent to which one phase depends on the completion or performance of another.

Planning progress provides important milestones

Construction Enquirer says detailed consent has already been secured for Phase 5A, where Battersea Power Station Development Company and Wandsworth Council plan to deliver 200 council homes. Construction is targeted to begin in 2027. Work has also started at Prospect Place South, where Sisk is building two Gehry Partners-designed blocks containing around 300 homes, 65,000 sq ft of commercial space and a 15,000 sq ft community hub.

These milestones matter because major regeneration finance is typically assessed against what is deliverable now, not only the eventual masterplan. Detailed consent, active construction and clearly defined counterparties can give funders more tangible information on programme, procurement and cost exposure. By contrast, later phases may need financing assumptions to be revisited as designs and permissions develop.

Place-making has financial consequences

The proposals include new sightlines towards the Grade II* listed power station, landscaping intended to connect with Nine Elms Park, and a cultural venue called the Third Generator. These features support the plan’s emphasis on community and connection, but they also form part of the scheme’s delivery obligations and capital requirements.

Developers must demonstrate how public realm, cultural space and community facilities will be funded and sequenced alongside commercially income-producing uses. The value of such elements may be expressed through the quality and attractiveness of the wider destination, while their costs can arise earlier and require careful allocation between phases.

A broader lesson for long-term regeneration

Battersea illustrates why a masterplan should not be treated as a fixed financing blueprint. Over a long delivery period, design, demand and patterns of urban use can change materially. Reworking the remaining phases may protect relevance, but it also requires updated appraisals, delivery programmes and funding structures.

For developers and investors, the central financing lesson is the importance of optionality supported by clear phase boundaries. Large mixed-use projects need enough flexibility to respond to change, while retaining sufficient certainty for lenders to assess costs, security, dependencies and repayment. The revised Battersea plan provides a prominent example of that balance being addressed at masterplan level.
